False-inversion preventing control structure for anti-clamping system of vehicle window

Abstract

The invention discloses a false-inversion preventing control structure for an anti-clamping system of a vehicle window. The false-inversion preventing control structure is characterized by comprising a vehicle-window anti-clamping controller, wherein the vehicle-window anti-clamping controller periodically acquires values of a gravity acceleration sensor, input signals of a vehicle-window lifting switch, and door-lock or control signals of a BCM; after the vehicle-window anti-clamping controller performs synthetic judgment, the electric energy of a vehicle-mounted power supply is input to a glass lifting motor by controlling a relay to be closed, the motor rotates and outputs torque, and a glass lifter is driven through a worm wheel and a worm, so that the glass on a vehicle door is driven to ascend or descend. Through the adoption of the structure disclosed by the invention, the change of gravitational acceleration of a vehicle in the perpendicular direction during running is directly detected, so that the false inversion generated by road surface factors is eliminated, and the using experience of users is improved; the demand of a system for the calculating amount of the controller is reduced; the disturbance resisting capability of the system is improved; and the reliability is improved.

Description

technical field

[0001] The invention relates to the technical improvement of an automobile window anti-pinch system, in particular to an anti-mistaken reversal control structure for the automobile window anti-pinch system. Background technique

[0002] With the rapid development of automotive electronics technology, the technology and intelligence of automobiles are changing with each passing day. As a safety configuration, the electric window anti-pinch system is more and more applied to automobiles. However, due to the lack of comprehensive technology and different core control algorithms, the window anti-pinch system not only closes the window to prevent pinching, but also greatly increases the chance of the window being mistakenly reversed during the automatic window lift process. That is, when the car is driving on various special roads such as sand, potholes, steps and manhole covers, if the window is operated to automatically raise the window, the car may be overweigh...
